The Hydrogen Stream: Construction begins on world’s largest integrated green hydrogen, ammonia plant

Posted by in categories: government, solar power, sustainability

Solar energy and onshore wind are crucial to unlocking Africa’s hydrogen potential, the International Energy Agency (IEA) said in its Africa Energy Outlook 2022. “With further cost declines, Africa has the potential to produce 5 000 megatonnes of hydrogen per year at less than $2 per kilogram,” reads the report. The continent has 60% of the world’s best solar resources, but only 1% of its operational solar generation capacity.

Serbia and Hungary signed a memorandum of understanding to collaborate on renewable hydrogen. “The signed memorandum is the basis for exchanging documents in this area and discussing potential joint projects,” said the Serbian government.

New magnet breakthrough could unleash smaller, more potent fusion reactors

Posted by in categories: innovation, nuclear energy

Nuclear fusion promises practically limitless energy and an unshackling from the harmful impact of fossil fuel consumption.

Now, researchers from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) announced they found a way to build powerful magnets much smaller than ever before, a press statement reveals.

Interesting Engineering.

DayDreamer: An algorithm to quickly teach robots new behaviors in the real world

Posted by in categories: information science, robotics/AI

Training robots to complete tasks in the real-world can be a very time-consuming process, which involves building a fast and efficient simulator, performing numerous trials on it, and then transferring the behaviors learned during these trials to the real world. In many cases, however, the performance achieved in simulations does not match the one attained in the real-world, due to unpredictable changes in the environment or task.

Researchers at the University of California, Berkeley (UC Berkeley) have recently developed DayDreamer, a tool that could be used to train robots to complete tasks more effectively. Their approach, introduced in a paper pre-published on arXiv, is based on learning models of the world that allow robots to predict the outcomes of their movements and actions, reducing the need for extensive trial and error training in the real-world.

Russia announces an official exit from the ISS — surprising its decades-long partner NASA

Posted by in category: space

But Lindgren received an abrupt request to comment on the day’s big news: the new Russian space chief Yuri Borisov said the nation, which has been a steady NASA partner in space and that has ferried American astronauts up to the ISS as recently as 2020, would end their decades-long space station collaboration.

The news spread on Tuesday after the Kremlin published a transcript meant to represent a dialogue between Borisov and President Vladimir Putin, in which Borisov tells Putin that Russia will end their partnership on the ISS in 2024.
